598 |
Helper function that rewrites all subsequent extended_attributes queries to match the alias generated by the dbic self left join |
599 |
Take the below example (patrons), assuming it is the third instance of an extended_attributes query: |
600 |
{ |
601 |
"extended_attributes.value":{ |
602 |
"like":"123%" |
603 |
}, |
604 |
"extended_attributes.code":[ |
605 |
[ |
606 |
"arbitrary_attr_code", |
607 |
"another_attr_code" |
608 |
] |
609 |
] |
610 |
} |
611 |
|
612 |
It'll be rewritten as: |
613 |
{ |
614 |
"extended_attributes_3.value":{ |
615 |
"like":"123%" |
616 |
}, |
617 |
"extended_attributes_3.code":[ |
618 |
[ |
619 |
"arbitrary_attr_code", |
